Lichen Planus and Lichenoid Disorders
Lichen is a rather common chronic inflammatory, immune-mediated disease which affects the skin and the mucous membranes; it occurs in Caucasian and in pigmented skin populations without ethnic predilection. The clinical manifestations represent a non-specific mucocutaneous reactive pattern, precipitating after diverse irritating factors and environmental conditions. It seems that individuals with heavily pigmented or black skin are predisposed to develop a lichenoid response after chronic irritation.
